内部服务器错误-Opencart

Question

我已经在本地服务器上下载了opencart安装，以便将其用作测试，但无法查看该站点。 当我使用默认的htaccess文件时，浏览器返回500错误，而当我删除htaccess文件时，seo-链接不起作用。 （404）

有任何想法吗？

我的.htaccess文件

### Additional Settings that may need to be enabled for some servers
### Uncomment the commands by removing the # sign in front of it.
### If you get an "Internal Server Error 500" after enabling any of the following settings, restore the # as this means your host doesn't allow that.

# 1. If your cart only allows you to add one item at a time, it is possible register_globals is on. This may work to disable it:
# php_flag register_globals off

# 2. If your cart has magic quotes enabled, This may work to disable it:
# php_flag magic_quotes_gpc Off

# 3. Set max upload file size. Most hosts will limit this and not allow it to be overridden but you can try
# php_value upload_max_filesize 999M

# 4. set max post size. uncomment this line if you have a lot of product options or are getting errors where forms are not saving all fields
# php_value post_max_size 999M

# 5. set max time script can take. uncomment this line if you have a lot of product options or are getting errors where forms are not saving all fields
# php_value max_execution_time 200

# 6. set max time for input to be recieved. Uncomment this line if you have a lot of product options or are getting errors where forms are not saving all fields
# php_value max_input_time 200

# 7. disable open_basedir limitations
# php_admin_value open_basedir none

Answer 1

通常， .htaccess文件的语法非常敏感，任何错误都可能引发http 500错误。 错误可以链接到httpd升级后不支持的语法错误和/或指令。

我建议您通过制作.htaccess的备份副本来逐步进行测试，并从空白文件开始添加一些部分，直到服务器出现错误为止。

如果有，请考虑自然解决问题。

Answer 2

在OpenCart中调试500个服务器错误时，要做的第一件事是查看服务器的错误日志并找到确切的错误消息 。

如果没有，则可能需要通过在PHP配置中调整error_reporting ， display_errors和log_errors设置来显式启用它们。 您也可以直接在主index.php文件中临时更改它们。

知道确切的错误消息后，对其进行修复是一个简单的过程。

我们在博客文章中介绍了一些导致500个服务器错误的最常见的OpenCart错误消息： OpenCart中的服务器错误和空白页：最常见的原因 。

我建议不要尝试在无法查看错误日志的情况下修复空白页和500个服务器错误。 这些问题可能是由从服务器配置以及受限的OpenCart代码的限制开始的几乎所有事情引起的，因此您确实需要知道要处理的内容。

在您的特定情况下，这很可能是由于您的服务器配置禁止将特定规则放置在.htaccess文件中引起的。
